Absolutely terrible shocking service from this shop. Do not trust this place one bit with your vehicle. Spend your hard earned money elsewhere. Dont know how they have lasted this long.

By far the best shop I have been too, I took my car in for a trans service and Daniel went over the whole car and showed me additional concerning issues that I was not aware of. He was very understanding with the budget I had and worked with me amazingly! 10/10 recommend any M113k platform to come here as he is a genius with them. Really appreciative of the fantastic work and the short time line he provided.

If I could leave 0 stars I would, the unprofessional attitude and way business is conducted is repulsive. I called and scheduled to have my car scanned for a check engine light and they told me they would not help in any way. That all the lifts we’re full and they could not scan my car??? How do you need a lift to scan my car? I was spoken to rudely on the phone and told to go somewhere else where I was wanted. If I were you I would take your business to a shop that cares about the customers.

They will hold your car hostage and lie to you about work that isn’t even being done to your car. STAY AWAY.

My husband only trusts Daniel. He researched all over Indiana and Illinois and he shipped his car to him because he knew Zealous was the shop to use. HE was in constant contact with my husband and he updated him thru the whole journey. Daniel is one of a kind and Zealous is that shop to trust.

Daniel worked on my highly modified 2013 AMG C63 and quite frankly I cannot remember last time I was this pleased with ANY service. The car was experiencing random ghost misfires through cylinder banks 1-4 and occasionally 7. I personally replaced all plugs and coil packs and when this did not solve the issue, I knew I needed more insight. After diagnosis Daniel found that the 8 fuel injectors were all in terrible shape, sporadically spraying or withholding fuel and needed to be replaced. I have personally been in this car game for 30 years and have yet to encounter somebody as well versed, mechanically intelligent, organized and understanding as Daniel. He will work with you in all ways possible and actually LISTEN to your cares, concerns and overall insight. He treats all vehicles like his own and is an expert on many platforms, especially AMG M156 motors. To close, I have never felt more reassured that if my driving breaks something, there is a fair priced and EXPERT mechanic to fix. 120% recommend Zealous Performance to anyone.

Got my Alfa Spider taken care on routine maintenance and some oil leak.Job was done professionally and price was reasonable!Thanks for great and affordable service!

STAY AWAY if you dont want your car to be locked up and charged storage fees as well while nothing gets done on the car!

Been taking my Jaguar F-Type R here for about a year. I have had everything from oil changes to engine repair done at Daniels shop and am always very satisfied with the quality of his work. He is very fair on pricing and good about actually showing you what is wrong with your car. Very professional, highly recommend you take your car here if you want the work done right.

This shop is by far the best I have ever gone to for Mercedes repair and service Daniel is knowledgeable, fair on prices and honest been there for new radiator, new alternator, rear main seal(oil change of course) and will be going for coil overs next. All done flawlessly all done on time no complaints gained a Long time customer!

Let me tell you about the smartest mechanic known to man. I had some issues with my 2004 S55 Amg and I was wondering where to get all my service done and modifications done. So one day I was searching the web and found out this smart man Daniel he is one of the best mechanic’s in the world. I came to Daniels shop one day and asked him a few questions and right away he knew the answers and the deals. This guy is one of a kind, quick, smart, and a reasonable guy. Please check out his shop.

Daniel went above and beyond to get my car done right. Very professional and great pricing. I highly recommend zealous performance!

Great pricing, amazing work quality and also uses the best quality parts!

I have owned many vehicles over the years and Ive never been treated so poorly in my life. After five and a half months and being charged 30% more than what was quoted I ended up towing my vehicle away from his shop uncompleted. His excuse was he had other cars to work on and couldnt get back on it for a month or so. Absolutely horrible experience. BUYER BEWARE!!!DANIEL DOESNT DO WHAT HE SAYS HES GOING TO DO. 6 month s after dropping it off I still dont have a running car and I spent $1,200 more than what was quoted. $5,000 out of pocket for a car that doesnt run. There are many issues to be fixed before this car is going to be drivable. I wish I had never set foot into Zealous Performance.

Zealous Performance is by far the best shop I’ve taken my Mercedes to! They treat you like family at there facility and the quality of there work and attention to detail they have is outstanding! They have earned a lifetime customer! I recommend Zealous Performance for all you services and repairs on any European vehicle as I saw in there shop they are well versed in many European and exotic vehicles!!

Broke my engine and overcharged me on my porshe never again stay away from this dishonest place

Absolutely best shop I’ve been to in the area for performance and builds. The staff understood what I wanted and was very clear with me on costs - literally can’t beat their prices after comparing to other shops. Highly recommend this place, ask for Dan.

Hack shop and complete fraud.

This professional car mechanic in Villa Park was recommended to me by my friend. I received a quick help at affordable prices. The car fault was easily fixed and thanks to that I could continue my route.

Stand up mechanic. Ive been utilizing him for all my Mercedes & BMW needs for 3 years & counting. He is very meticulous in making sure his work on my vehicles is done properly & Im thankful to have found him.

I was pleased with your oil change service in Villa Park because it was done quickly but very efficiently. The oil change that was done was perfect and would definitely come back here if I need any car repair in Villa Park.

Amazing prices, great services!

Great customer service and car repair shop. Will return and send referrals. It’s hard to find a good Euro shop that does excellent work at an affordable rate.

Brought my 2011 BMW 335xi in for coolant pump and thermostate and to address a headlight fault and Zealous Performance took care of it with no issues completed the job correctly and for an amazing prize!

Took my 2009 Mercedes E63 AMG in and was very impressed by the service and the knowledgeable the owner had on my AMG but on all the other AMG platforms. By far the best experience I’ve every had at any shop and will be coming back for all my repairs and also performance mods for my car! I highly recommend this shop for all your European service,repair and performance needs!!!

They are a professional auto repair company in Villa Park. After an oil change service, I asked them to check my car. They advised me for some important things that needed to be fixed. They charged me for a fair price, and I’m ready for the road again.

Great & kind professional friendly service .

Very bad guys, be careful

The only place I would bring my AMG
